Technical Field

[0001] The utility model relates to the technical field of carton production, in particular to a material pressing and conveying component and carton forming equipment. Background Art

[0002] Carton forming equipment needs to transport the flat-stacked cartons to a set position for gluing, folding, and other procedures.

[0003] Currently, carton forming equipment generally uses a conveyor belt to transport flat cartons. However, this method easily causes the cartons to slip relative to the conveyor belt, resulting in poor conveying efficiency and difficulty in flattening the cartons. Of course, there are also carton pressing devices that use a downward pressing component to press the carton flat, but if there are hard objects inside the carton, it will easily cause the carton to break.

[0004] In view of this, it is necessary to design a material pressing and conveying assembly and a carton forming device that can integrate the functions of conveying cartons and flattening cartons, and can help avoid crushing the cartons.

[0005] The above information is presented as background information only to assist with an understanding of the present disclosure and is not a determination or admission that any of the above may be applicable as prior art with respect to the present disclosure. Utility Model Content

[0044] Example 1

[0045] In view of the aforementioned deficiencies in existing carton conveyor assemblies, the applicant, drawing upon years of extensive practical experience and expertise in the design and manufacture of such products, combined with the application of academic knowledge, has actively engaged in research and innovation, hoping to create a technology that can address the deficiencies of the existing technology and make press-feed conveyor assemblies more practical. Through continuous research and design, as well as repeated trial production and improvements, the present utility model, which is truly of practical value, has been created.

[0046] Please refer to Figures 1 to 3The embodiment of the present invention provides a pressing and conveying assembly for conveying cartons, comprising: a support plate 1, which plays a supporting role; a conveying roller group 2, on which the cartons are placed for conveying, and the conveying roller group 2 is installed on one side of the bottom of the support plate 1; a pressing belt assembly 3, which is installed between the conveying roller group 2 and the support plate 1, and comprises a support frame 31, an active pulley 32, a passive pulley 33, a driving motor 34 for driving the active pulley 32 to rotate, and a pressing belt tensioned on the active pulley 32 and the passive pulley 33; both the active pulley 32 and the passive pulley can be rotatably mounted on the support frame 31, and the driving motor 34 is fixedly connected to the support frame 31; an adjusting cylinder 4 is installed on the support plate 1, and the telescopic shaft of the adjusting cylinder 4 is fixedly connected to the support frame 31 to at least offset part of the gravity of the pressing belt assembly 3.

[0047] In the actual production process, the flattened carton is placed on the conveyor roller group 2, and the pressing belt assembly 3 is pressed on the carton. The pressing belt is pressed on the carton, and the driving motor 34 drives the active pulley 32 to rotate so that the pressing belt drives the carton to be conveyed forward; when there is a harder block inside the carton, the harder block will apply an upward force to the pressing belt when it enters the bottom of the pressing belt. The upward force cooperates with the adjusting cylinder 4 to enable the pressing belt assembly 3 to rise and fall upward, thereby avoiding crushing the carton.

[0048] For example, the weight of the press belt assembly 3 is 100N, and the upward pulling force of the adjusting cylinder 4 on the press belt assembly 3 is 95N. When the upward force of the block on the press belt assembly 3 is greater than 5N, the press belt assembly 3 rises and falls upward; of course, the upward pulling force of the adjusting cylinder 4 on the press belt assembly 3 can be adjusted according to actual needs, and the above values ​​are only examples.

[0049] Optionally, the pressing surface of the pressing belt is parallel to the conveying surface of the conveying roller group 2. In this way, the entire pressing surface is pressed on the top surface of the carton to avoid the carton from slipping relative to the pressing belt.

[0050] Optionally, the support frame 31 includes a first frame body 301 and a second frame body 302; the driving pulley 32 is installed on the first frame body 301, and the driven pulley 33 is installed on the second frame body 302; two adjusting cylinders 4 are installed on the support plate 1, and the telescopic shaft of one adjusting cylinder 4 is connected to the first frame body 301, and the telescopic shaft of the other adjusting cylinder 4 is connected to the second frame body 302.

[0051] Specifically, when a harder block enters under one regulating cylinder 4, the pressing belt directly under the other regulating cylinder 4 is still maintained on the top surface of the carton, thereby making the transportation of the carton more stable.

[0052] Optionally, the press-feed assembly further includes a frame 100 and a lifting drive assembly 5. The lifting drive assembly 5 includes a mounting plate 51 fixedly connected to the frame 100, a drive assembly 52 mounted on the mounting plate 51, and a lead screw fixedly connected to the support plate 1. The drive assembly 52 includes a lead screw nut mounted on the lead screw and a lifting motor 521 for rotating the lead screw nut. The drive assembly 52 rotates the lead screw nut, thereby raising or lowering the support plate 1. The lifting motor 521 drives the lead screw nut through a reduction gearbox and a transmission rod.

[0053] Optionally, the regulating cylinder 4 is connected to a pressure regulating device, which is used to regulate the air pressure in the regulating cylinder 4. The pressure regulating device can adjust the force of the regulating cylinder 4 on the pressing belt assembly 3.

[0054] Optionally, the pressing and conveying assembly also includes a side pressure assembly 6 installed on the conveying roller group 2 and a vertical roller group 7 for positioning the carton, the vertical roller group 7 includes a plurality of vertical rollers arranged at intervals along the conveying direction of the conveying roller group 2; the pressing belt assembly 3 is installed between the vertical roller group 7 and the side pressure assembly 6, and the side pressure assembly 6 can push the carton toward the vertical roller group 7.

[0055] The cartons are generally conveyed between the vertical roller group 7 and the side pressure assembly 6. The side pressure assembly 6 pushes the cartons toward the vertical roller group 7 so that the side edges of the cartons contact the vertical roller group 7, making the subsequent glue spraying position or folding position more accurate.

[0056] Optionally, at least two regulating cylinders 4 are arranged at intervals.

[0057] Optionally, the pressing belt is a grass-patterned conveyor belt.

[0058] Optionally, a belt guide 8 is further installed between the first frame 301 and the second frame 302. The belt guide 8 can effectively limit the position of the pressing belt, prevent the pressing belt from sagging too much, and keep the pressing position of the pressing belt in a relatively straight state.

[0061] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concepts of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
